Fix : GRUB_BTRFS_LIMIT (Limit the number of snapshots populated in the GRUB menu.)

Fix : When a value =< 0, script stop correctly
fix : When a value => 1, script stop when the value is reached

e.g :
 - GRUB_BTRFS_LIMIT="0"
   script doesn't detect snapshot

 - GRUB_BTRFS_LIMIT"1" or "2" "etc..."
   script will stop the snapshot detection when value is reached
